Part of the present inflation is caused by the breakdown of globalization, in particular supply chains, part is caused by the Corona Pandemic, in particular lockdowns, part is caused by the Ukrainian War, part is caused by European sanctions, and part - and not the smallest one - is caused by...

In this paper we empirically investigate the time- and state-dependent behavior of aggregate price setting. We implement a testing procedure by means of a nonparametric representation of the structural form New Keynesian Phillips curve. By means of the so-called functional coefficient regression...

This paper studies monetary regime choice between monetary union and flexible exchange rate regime in a large open economy framework. The classical approach emphasizes that monetary unions are inherently costly because a single interest rate cannot respond effectively to different shocks of...

When indexation is endogenous price level targeting slightly adds to economic stability, contrary to widespread fears to the contrary. The aggregate supply curve flattens and the aggregate demand curve steepens, increasing stability in the face of supply shocks.

We investigate changes in the time series characteristics of postwar U.S. inflation. In a model-based analysis the conditional mean of inflation is specified by a long memory autoregressive fractionally integrated moving average process and the conditional variance is modelled by a stochastic...

We use a variety of nonparametric test statistics to evaluate the inflation- targeting regimes of Australia, Canada, New Zealand, Sweden and the UK. We argue that a sensible approach of evaluation must rely on a variety of methods, among them parametric and nonparametric econometric methods, for...

In line with the recent developments on the statistical analysis of functional data, we develop the semiparametric functional autoregressive (FAR) modeling approach to the density forecasting analysis of national inflation rates using sectoral inflation rates in the UK over the period January...

We investigate inflation persistence in six inflation targeting (IT) countries from the global-economy perspective. This view maintains that inflation persistence in IT countries has declined mainly because of the decline of inflation persistence in the global economy. We provide empirical...

This study examines the information flow between inflation and inflation uncertainty (IU) and intrastate inflationary trend among some ECOWAS member states. IU is measured using GARCH models and stochastic volatility model (SV). Transfer en- tropy was adopted to quantify the extent of...

This paper explores the existence of downward nominal wage rigidity (DNWR) in the industry sectors of 14 European countries, over the period 1973-1999, using a data set of hourly nominal wages at industry level. Based on a novel nonparametric statistical method, which allows for country and...
